Illegal, Unreported, and Unregulated (IUU) Fishing poses a global challenge and has significant economic and environmental repercussions. [5] The impact of IUU fishing includes economic losses, job losses, scarcity, price distortion, food insecurity and unfair competition, [6] together with the depletion of fish populations and damages to the marine habitat. [7]
It has been estimated that 50% of the Caribbean Sea coral cover has disappeared since the 1960s. According to a United Nations Environment Program report, the Caribbean coral reefs might face extirpation in next 20 years due to population expansion along the coast lines, overfishing, the pollution of coastal areas, global warming, and invasive ...
Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
Ray Hilborn stated that the unsustainable nature of fisheries can be characterized by three aspects: . Inconsistent long-term yield refers to the imbalance in nature when fishing is practiced improperly, which results in the inability to capture the maximum sustainable yield at a regular and predictable rate.
The overfishing list reflects species that have an unsustainably high harvest rate. NOAA also keeps a list of overfished stocks. Those are species that have a total population size that is too low.
Between 1993 and 2018, the mean sea level has risen across most of the world ocean (blue colors). [71] Coastal ecosystems are facing further changes because of rising sea levels. Some ecosystems can move inland with the high-water mark, but others are prevented from migrating due to natural or artificial barriers.

The Central American Seaway (also known as the Panamanic Seaway, Inter-American Seaway and Proto-Caribbean Seaway) was a body of water that once separated North America from South America. It formed during the Jurassic (200–154 Ma ) during the breakup of the supercontinent Pangaea , and closed when the Isthmus of Panama was formed by volcanic ...
